` Application filed June le;

To all whom `it may concern:

i Be it known that lI, `i?itinere Fplliinson, a citizen i of the UnitedStates, residing inr Hollisteigcounty of San Benito, and State of California, have invented a new and use# ful Improvement .in a `Pulling Jack, of which the following' is a specification.

My invention relates to iniproveinents in a jack provided with anelongated ratchet bar arrangedto move an object by a direct pressureor `by a tension created inray connecting member. y

rllhe primary object of` my inventionis to provide an improved jack `adapted for applying either pressure or` tension. i

Another object is to provide improved securing means facilitating the anchoring of a jack. i

A further` object is to provide improved means engaging a connection to an objectA to be moved to facilitate the moveinentof, said object by means of "a pulling force applied through said connection.

A further object is toV provide an im-` proved jaclr. of the character described arranged to give aninereased range of movement. y

A still further object is toprovide a simplified construction vadapted to be` manufactured at a. reduced cost. l

'I accomplish these and other objects by means ofthe device disclosed in the draw-` ingsforming a part of the present specification wherein like characters of reference' are used to designate similar parts throughout said specification anddrawings, and,in which:

R'eferringto the drawings the numeral l 192i. seriai normalem is used to designate in general a housing having a notch2 formed in the one edge thereof, and provided with an outwardly extending lip 3 arranged to engage any convenient portion of an object to beQmoved by direct pressure iii a mannerliereinafter described. y

j A bar e formed prefer iron extends longitudinally through ythe housing l, the tops'ofthe channel flanges being provided with ratchet teeth Gas bestl disclosed in Fig.y l of the drawings. f The barl may be made of any desired length to permit rangeof movement suited' to the individual requirements of the user. t

A pair of pawls 7 and Sare mounted within the housinglfin operativeengagenient with the ratchet teetli `upon an operating lever socket 9 pivotally mounted within the housing l. Ani operating lever ll is remoifably engaged the socket 9 to afford a suitable leverage for operation t ofthe pawls. t

.er spring l2 is mounted between the pawls 7 and S to hold the same inoperative engagement with the teeth 6, the paivl 'l' be-V ing moved by the leversoclret -9 `to engage successive teeth 6' for advancing the bar' l throughth'e housing l, and the pawl 8 be `ing -held in engagement with successive teeth- 6 to prevent backward movement of the bar 4 when thepawl 7 is moved to engage each succeeding tooth. A lever l provided ably from channel with :in extending lug ltj'is pivotally Y.

in-ountedlupon `the lhousing l adjacent the spring l2. The lugv 14 normally depresses the springl l2 to hold the pawls and 8 in operative position as above described, i as y sliownin fullilines iiivFig. l. The lever 1?) extends outwardly through aslot 1G in the housing 1 and may be moved to the posi-r tion shown in dotted lines to release the spring l2, thereby `perinitting the p awls and 8- to disengage the ratchet teeth 6to permit the bar d to be `moved through the housing independently ofthe"` pawls.`

Cleats 1'? having outwardly 'turned ends 18 yare securedupon the sidesof the hous-` ingl.y one of said cleats 17 having one end cfa chain 19 secured thereto, and the other cleat -17v being provided y with a hook y 21 adaptedto engage a linlr in the chain 'in a manner hereinafter' more fully described.

@ne end ofthe bar 4 is provided with a lug 22 upon which is pivotally mounted a clutch member 23 having an eccentric serrated surface 24 arranged to engage a vvirev 26 or other connecting member and hold the same rigidly against `the bar l as shoWn in F ig. 6 of the drawings, an increase in tension 1n the connection 26 causing the same to be more firmly gripped by the inem# ber 23.l A hook 27 may be formed upon the member 23 to engage ak chain or other connection not suited for engagement be-` tvveen the surfaceV 24 andthe bar l. `suitable linlr 28 or cl'evis `may also bei mounted at the end of the bar el to further iaoihtate the .attachingofa connection 26 Y, to the bar.

The other endo'f the bar l is provided with Aa shoe 29 removably7 secured to the bar by a pin 31the shoe 29 providing` bearing surface to rest upon the 'groundro ypermit an Aobject to be raised by direct pressure as l" vhereafter' described.

My invention isl designedfprimarily 'for exerting a pulling torce upon an object to be f moved, the applicationyof my ldevice :tor

pulling a vehicle 30 out of a mudhole or the like` being illustrated in Fig. 3 of the drawings. The operation of my invention in this connection is as follows: I 4

The housing 1 is anchored/togay fixed object suchfas a stake 82 driven into the ground a suitable distance in advance of the vehicle or to any convenient post or tree should` either beat hand, by making aloop ofthe chain l9gliromthe cleat 17, to Which the chain is, permanentlysecured, around the stake 32 or other fixed object, the chain 19- beingbrought backthrough the notch and a second loop made about the stake 32, the

free end ofthe chain being then brought p. into engagement with the hook 2l. In ythis 23 as above described.

. andr causinga pulling force to be exertedA manner the housing` l is-anchored from tivo now be oscillated to cause the pavvl 7 to engage successive teeth 6 and advance the bar 4 longitudinally through the housing l, in this manner creating a tension in the Wire 24;

upon the vehicle.`

`It vsometimes 4happens that the front Wheels of a vehicle become mired in a mud holein such a manner that a footing cannot be had for the application of a jack in the usual manner. ln this event, my improved -device may be connected in the usual man-V ner abovek described to a beam 38 suitably supported above the portion ot the'vehicle The lever 11 may to be raised'as illustrated in Fig. 4 of the drawings. Movement or' the bar 4 through the housing 1 anchored inthisl fashion will pull the vehicle upwardlyy tothe desired to' the end oi lthe ba-r l to rest upon thev ground or other Supporting surface. lThe housing l is now advanced alongthe bar 4 until the lip 3 is brought into engagement with a rigid portion ot thehvehicle such as` the axle Uperation of the pawls Zand 8 by the lever il will new operate to move the housing vil relatively to the bar 4- Which is4 rigidly supported upon the ground, thereby causing the lip 3 to move the vehicle up- Wardly a corresponding amount.' e

While "l have illustrated my invention in reference to its utility for lifting and moving a vehicle, the device is equally useful lfor moving any other heavy object, the opbar extending longitudinallyv through saidv i cured at the other end thereoie to the' other cleat tor anchoringsaid housing to a fixed object; and means mounted upon one end ot y the ratchet bar to engage a connection to u object to be moved whereby movement ol'i the bar through the housing operates to 'exert a pulling force upon said object to be moved. 2.
